And referring to the structure shown at Figures 2, 4 and 6, if the edges of the part 3 were retracted, the lips 8, 9 would enter farther within the part 3 and the cable could be clamped, since this would prevent the abutment of these shoulders and edges.

In other words, the cable opening between the hook and part 3 can be made more or less by the location or extent of these shoulders and edges.

In all instances the cables are tautened at the end posts before any clamping of such cables in the manner described, and also preferably before the fixtures of loose running cables are secured to the posts.

Referring particularly to Figures 2, 4 and 6, the base 2 is of any conventional form with its inner edge conformed to the post l which is round in cross-section, although the lateral contour of the post is immaterial, this particular form of post being shown merely as a variation. The bolt, which is designated by 5, is rigid with the head 6 is threaded at its outer end and extends through said base and post, and a nut I6 is driven on said threaded end of the bolt against the post to clamp the fixture'to the post. In all other respects this construction is the same as that shown in Figures 1, 3 and 5, except that the shoulders of the bolt head are shown abutted against the edges of the crescent shaped part 3 of the base, in order to show how this fixture may be adapted for a loose running cable, but, as before stated, either form of the fixture is adaptable for a tightly clamped cable or a loose running cable, and, therefore, this invention is not limited in this respect,

I have illustrated and described a preferred and satisfactory embodiment of my invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof as defined in the appended claim.

What is claimed is:-

In a highway guard cable fixture comprising a base member adapted to engage a post, said base member being inwardly recessed at the end thereof to form a cable receiving pocket, and means for attaching said fixture to said post, a hook member for attaching said cable to said base member, said hook member being provided with a head for closing the recess in said fixture, means for distributing the impact of a blow evenly over the edges of the recess comprising flanges on the hook member engaging the edges of the recess throughout their length.
